General description:
There are only two motorways: the A1 Bucharest (Bucuresti)-Pitesti and the A2 Bucharest-Constanta. The A2 appears as 'A3' on many maps.
The DN and DJ roads have a common zone system based on the first digit of each number. Romania has been divided into seven zones bounded by trunk roads which radiate in clockwise order from Bucuresti. Each zone bears the number of the road bounding it upon the left, facing outwards from the centre. Therefore there are no numbers beginning with 8 or 9. Within each zone, road numbers generally increase as a function of the shortest distance to Bucuresti. This holds more strictly for DN numbers than for DJ numbers. Zone 7 consists of two isolated parts because the DN1 and DN7 follow the same route between Sibiu and Sebes. Because of the non-central location of Bucharest, zones 3 and 4 are very small, while zone 1 is very large.
DJ numbers are sometimes also referred to as just 'D' roads (drum=road). DJ numbers are derived from DN numbers by adding a digit at the end (for 2-d numbers, e.g. DN18 > DJ182) or a zero and a digit (for 1-d numbers, e.g. DN1 > DJ108).
There are many numbers with a letter suffix. These are not necessarily less important than the corresponding unsuffixed numbers.
Communal roads are numbered per county.
